As somebody who administers a VMware digital atmosphere and has been by way of a number of firm mergers, working stock audits is second nature to me. It is at all times a good suggestion to keep up a present stock of your digital machines with the intention to greatest handle the atmosphere, however as a result of ever-changing nature of know-how, the place techniques are constructed or decommissioned at an everyday tempo, it may be like attempting to hit a transferring goal.

As common, scripting is the important thing right here. This VMware-based PowerShell script will help make amassing your stock information fast and simple. My colleague Brad Doran, senior technical account supervisor at Amazon Net Providers, offered me this script and I’m utilizing it right here together with his permission. You possibly can copy and paste it to an area file referred to as VMware_Inventory.ps1, for example.

Conditions

Use Home windows 10 (it is theoretically attainable to run this in Home windows 7, however it’s possible you’ll expertise complications with outdated PowerShell variations since this script requires PowerShell 4.0 at minimal).

Run Home windows PowerShell ISE as Administrator (you can too use common PowerShell, however I discover ISE greatest for optimum outcomes in addition to error analysis).

Set up the VMware PowerCLI module utilizing this remark inside the PowerShell ISE Window:

Set up-Module -Identify VMware.PowerCLI

In case you get an error that you simply want NuGet supplier model 2.8.201 simply click on Sure and the method will obtain and set up it for you. It’ll take just a few moments and you may then have to click on Sure to proceed, and in just a few extra moments you will notice this system putting in the associated VMWare.PowerCLI packages.

Because the script requires the VMware.VimAutomation.Core module additionally make sure that it is the most recent model (as of October 2021) put in through this command:

Set up-Module -Identify VMware.VimAutomation.Core -RequiredVersion 10.0.0.7893909

Click on Sure to proceed and in just a few extra moments you will notice this system putting in the associated VMWare package deal.

In case you obtain an error stating: “PackageManagementInstall-Bundle : Authenticode issuer ‘CN=VeriSign Class 3 Public Main Certification Authority – G5, OU=”(c) 2006 VeriSign, Inc. – For approved use solely”, OU=VeriSign Belief Community, O=”VeriSign, Inc.”, C=US’ of the brand new module ‘VMware.VimAutomation.Core’ with model ‘10.0.0.7893909’ is just not matching with the authenticode issuer ‘CN=DigiCert Trusted Root G4, OU=www.digicert.com, O=DigiCert Inc, C=US’ of the previously-installed module ‘VMware.VimAutomation.Core’ with model ‘12.4.0.18627056’. In case you nonetheless wish to set up or replace, use-SkipPublisherCheck parameter”

run this command:

Set up-Module -Identify VMware.VimAutomation.Core -RequiredVersion 10.0.0.7893909 -SkipPublisherCheck

You can even go right here and obtain the most recent model to (“C:Program Recordsdata (x86)VMWareInfrastructurePowerCLIModules”):

Customizing the script

The script depends on these variables (Determine A):

$vcs = @(“vCenterFQDN”) # FQDN of your vCenter server.
$logFile = “C:TempVMInventory.csv” # The place you wish to save the CSV file
$vcsCluster = “*” # Filters which cluster you wish to pull VM stats from
$businessUnitName = “Factor” # Identify of enterprise unit that the script is gathering stats for

Determine A

For $vcs, you’ll be able to change @(“vCenterFQDN”) with the identify of your vCenter server in quotes; in any other case the script will immediate you to enter the identify.

For $logFile, the logfile path and identify may be modified accordingly.

For $vcsCluster you’ll be able to specify the cluster to collect information from, or depart this line as is to drag data from all clusters.

For $businessUnitName, change the instance “Factor” entry with your small business unit, division or group.

Working the script

Click on File then Open and browse to the place you saved the script file to pick it then load it into PowerShell ISE. Hit the inexperienced button to execute it. 

In case you get an error associated to safety insurance policies or the script being unsigned, run this command to permit native scripts and distant signed scripts:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned 

In case you left the $vcs variable as is you can be prompted to enter the vCenter server identify (Determine B).

Determine B

When you enter the identify you may be prompted to authenticate to vCenterj (Determine C). Be sure to make use of an account with administrator-level credentials.

Determine C

You’ll then see the script working and actively gathering information (Determine D).

Determine D

The script will show the outcomes, in addition to save the main points to “C:TempVMInventory.csv” in the event you left the associated variable as is (Determine E).

Determine E

(Observe I’ve eliminated the FQDN entries that had been listed since this was run in opposition to an energetic enterprise atmosphere.)  

Thanks, Brad, for a wonderful software each VMware administrator ought to have of their toolkit!
